Their function is to miniaturize and visualize circuits, and they play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. Circuit boards use flip machines in the production process, which facilitate double-sided plug-in and patching of circuit boards.

The utility model can clamp and fix the two sides of the circuit board respectively by adjusting the two clamping plates at the same time, which increases the stability of the circuit board during the clamping and fixing process, avoids the problem of poor fixing effect and falling off during the flipping process when using compression springs for clamping and fixing, and can adjust the clamping and fixing to the left and right according to the size of the circuit board by adjusting the plates to be close to each other, solving the problem of limitations of poor clamping effect.

When the second pressure sensor on the inner wall of the fixed clamping frame installed on the movable plate is in contact with the circuit board to be clamped, the controller stops the further extension of the transverse cylinder, and starts the extension of the longitudinal cylinder built into the cavity to cause the longitudinal cylinder to push the movable clamping frame downward under the action of the connecting block. When the first pressure sensor arranged on the inner top surface of the movable clamping frame is in contact with the circuit board to be clamped, the controller stops the further extension of the longitudinal cylinder to facilitate the damage-free clamping of the circuit board. Compared with the prior art, semi-automatic "soft" clamping of the circuit board can be achieved, and the upper and lower split clamping structure has a good clamping effect, reduces clamping damage and improves the efficiency of the flipping machine.

When the second pressure sensor 17 on the inner wall of the fixed clamp frame 14 installed on the movable plate 7 is connected with the circuit board to be clamped, the controller 18 stops the further extension of the horizontal cylinder 10, and starts the extension of the longitudinal cylinder 9 built into the cavity 8, so as to cause the longitudinal cylinder 9 to push under the action of the connecting block 12. The movable clamping frame 13 moves downward, and when the first pressure sensor 16 arranged on the inner top surface of the movable clamping frame 13 is connected with the circuit board to be clamped, the controller 18 stops the further extension of the longitudinal cylinder 9 to safely clamp the circuit board. When the circuit board needs to be flipped, the stepper motor 4 installed on the left support plate 2 is started to rotate 180 degrees, prompting the movable plate 7 of the left support plate 2 to rotate 180 degrees, and then the right support plate 3 adopts the connecting column 6 and the other movable plate 7 connected to the bearing seat to rotate 180 degrees, so as to realize the flipping operation of the circuit board, so as to facilitate the double-sided plug-in and patch of the circuit board.
